Importance of vitamin D

[impact]

Key findings

Almost all hospitalized patients with COVID-19 enrolled in the study were vitamin D deficient (97%), 55% were severely vitamin D deficient (<25 nmol/L) and 42% were vitamin D deficient (<50 nmol/L); 3% had insufficient vitamin D levels (<75 nmol/L), and none had optimal vitamin D levels (Table 2).

This finding is in line with the international literature, linking low vitamin D levels with higher susceptibility to symptomatic respiratory infection, including COVID-19.

In our trial, we found a statistically significant correlation between vitamin D levels and ICU admission. The lower the vitamin D level, the higher the probability of being admitted to the ICU (14.2 nmol/L (n = 13) versus 25.1 nmol/L (n = 224); p < 0.0001). Furthermore, we found a statistically significant correlation between lower baseline vitamin D levels and longer hospital stay (r = -0.195; p = 0.003). Vitamin D levels were comparable by gender and age.

Read about Vit D and Covid early on before the vaccine was even on the horizon. So I started taking D3 (1000 iu) twice a day...cheap and easy, just in case the science was sound..

Thanks for that link..confirms it !!

Started a little over a month ago taking it daily till spring or the warm weather and the days get longer.

When I first started taking it close to a year ago Independent grocers were selling the chewables were selling for $5:49. Since then when reference was made to Vitamin D3 and covid 19 the price has escalated to $8:49 for the same bottle. Gauging at it's best....

Supplementation is important for older people because as you age your skin becomes thinner and unable to absorb enough from the sun. I suggest people start reading the labels on their groceries as traditional foods that once contained high amounts of vitamin D have for some reason had the level of nutrients diminished within the last 2 years.

"The purpose of this study was to find out whether sardines and mackerel are a good source of vitamin D such as wild salmon. It was hypothesized that both sardines and mackerel are a good source of vitamin D. Based on the results, sardines are a good source of vitamin D. One serving size (3.5 ounces, about 5 fish) of sardines has about 330.8 IU's of vitamin D3. This is equal to 66.2 IU's of vitamin D3 per fish. Mackerel on the other hand does not have as much vitamin D3 as sardines. A standard serving of mackerel (3.5 ounces, about 3 fish) has 81.6 IU's of vitamin D3. This is approximately 27.2 IU's of vitamin D3 per fish. Both mackerel and sardines are good sources of vitamin D3."

I'd thought mention of side effects may benefit prior to self medicating, might want to run it by your MD first.

You provided an exaggerated example. A daily vitamin supplement is nowhere near that dose.
Over the counter vitamins are safe and effective. Have been for decades and no need to consult a doctor.
If in doubt, blood work will tell the tale.

Your example would be more inline with drinking 40 ounces of whiskey every day.

Oh come on we are all about over exaggerating here. I stand talk to your MD before you get your advice from Dr. Forum

In November 2010, the Institute of Medicine's expert committee set a new "dietary reference intake" for vitamin D.

Assuming that a person gets virtually no vitamin D from sunshine -- and that this person gets adequate amounts of calcium -- the IOM committee recommends getting the following amounts of vitamin D from diet or supplements (Note that the IOM's upper limit is not a recommended intake, but what the IOM considers the highest safe level):

Infants age 0 to 6 months: adequate intake, 400 IU/day; maximum safe upper level of intake, 1,000 IU/day
Infants age 6 to 12 months: adequate intake, 400 IU/day; maximum safe upper level of intake, 1,500 IU/day
Age 1-3 years: adequate intake, 600 IU/day; maximum safe upper level of intake, 2,500 IU/day
Age 4-8 years: adequate intake, 600 IU/day; maximum safe upper level of intake, 3,000 IU/day
Age 9-70: adequate intake, 600 IU/day; maximum safe upper level of intake, 4,000 IU/day
Age 71+ years: adequate intake, 800 IU/day; maximum safe upper level of intake, 4,000 IU/day

That's not enough, says Boston University vitamin D expert Michael Holick, MD, PhD, professor of medicine, physiology, and biophysics, Boston University Medical Center. Holick recommends a dose of 1,000 IU a day of vitamin D for both infants and adults -- unless they're getting plenty of safe sun exposure.
